Process for the filling and simultaneous homogenization of bulk material in an essentially endless round pile.

The invention relates to a method for filling and simultaneous homogenization of bulk material in an essentially endless round pile or a circular storage mixed bed with a triangular cross-section of the dump area and roof-shaped slope areas on both sides, in the intermediate stage during construction of the heap, seen in the front view, a curved section from the top of the heap to the heap base or is provided to the ground.

In a known method (DE-PS 14 32 040) for continuous Homogenization of bulk goods in circular stores

with circular or spiral-shaped bulk material dump that Is piled up like a roof, is a transition section provided, the ridge or ridge line in the development essentially represents a straight line.

A fundamental disadvantage here is that only a small volume of bulk material can be stacked in the ends of the pile.

The above-mentioned method requires constant layer heights, which results in an undesirable constant variation in the speed of rotation of the stacker is required.

With a different arrangement of the heap according to "stacking-blending-reclaiming of Bulk Materials ", Wöhlbier, Trans Tech Publications, 1977, pp. 119-132, with direct dump connection, If the ends of the pile are provided parallel to each other, one pile is poured directly onto the other.

Inhomogeneity of the goods to be stacked cannot be avoided in the connection area between the two heaps.

In contrast, the invention is based on the object in the receiving area of the round heap or the circular storage mixed bed a relatively optimal or significantly larger bulk material volume of the stacked bulk material, while remaining the same Rotation speed of the stacking device and favorable homogeneity of the bulk material. In addition, the aim of the invention is to shorten the flow time of the bulk material significantly when building the stockpile and to protect the bulk material.

This object is achieved according to the invention in that following the heap crown, the transition sections from the heap crown to the heap base to the outside essentially

designed parabolic and with each down increasing layer thickness are provided.

It has proven to be advantageous that when the heap ridge is poured in a parabolic shape, a constant Rotational speed of the assigned space loader is provided.

Appropriately, with a view to a uniform distribution or homogenization of the bulk material through the Stacking device the preselected slope angle is relatively flat.

In a preferred variant of the invention, the transition section, which is designed as a walking route, has a essentially larger bulk material volume formed in the entire area

The invention is explained in more detail below with reference to an exemplary embodiment shown schematically in the drawing.

It shows:

3 shows the arrangement of the stockpile with 'opposite straight lines

Layers - doubled the number of individual layers.

In the intermediate stage during the construction of the heap, a section of the heap crown A-B is followed

Transitional section on which the heap was built B-C between the top of the stockpile and the base of the stockpile is intended as a wandering route for the entire stockpile build-up.

This begins the build-up of the heap and is carried out over the parabolic outward transition sections B-C continued, which are provided with each downwardly increasing bulk volume. Through the parabolic configuration of the heap embankments is an essentially double heap or. Storage volume achieved.

Another important procedural effect is a relatively favorable homogenization, since when the heap is being filled up, one essentially doubles This guarantees a high number of individual layers in the cross-section of the heap compared to a conventional structure.

If, for example, with the conventional method, the speed of rotation of the stacking device is in the range of 0-20 m / min, with an average value of 10 m / min, has in the present method the Rotation speed approx. 20 m / min. When the total pile height is reached, double the number of Layers formed.

The stacking device is designed to be rotatable as well as liftable and lowerable, the speed of rotation with regard to the parabolic configuration is constant and the lifting speed is provided variable.

The functionality of the stacking device and the stacking device is provided so that the two devices not disruptive.

130040/0502

With the elimination of the pile ends, it is possible that the stacking device works continuously at full power.

By stacking the bulk material in the transition section B-C at a constant speed of rotation, it is also achieved that the flow time of the bulk material is significantly reduced.

In this process, the bulk material dump as a whole is built up essentially from below, which means that only small amounts of material are built up Bulk material routes are provided and protection of the bulk material is guaranteed.
